Output and Alarm Function Configuration
4.1 Output Functions
Outputs consist of control outputs and alarm outputs. Each channel can provide 2 control outputs and 3
alarm outputs.
4.1.1 Explanation of Output Functions
1. Control outputs: Can be set as heating outputs or cooling outputs. If an output is set as a heating
output, and another is set as a cooling, dual output control exists
2. alarm outputs: Up to 17 alarm modes can be independently set; please refer to [Section 4.3]
Notes: This device has an output percentage restriction function in PID and manual control (please refer to
[Chapter 5] for further information concerning control functions). Assuming that maximum output has been
restricted to 90% and minimum output to 20%, the calculated control output will be restricted to within a
20%~90% range
4.1.2 Physical Output Type
1. Control outputs: Relay output, Pulse voltage (0, 12V), analog voltage (0~10V), analog current
(4~20mA)
2. alarm outputs: Relay outputs
4.1.3 Output Function Settings
Hardware connections: The corresponding expansion cassette may be selected for the DTM host and
measurement expansion modules, or at the corresponding output module selected for an expansion IO
expansion module
Software settings: (communications addresses are shown in the table below)
A. OUTx control action: Setting content 0: Heating, 1: Cooling, 2: Channel disabled
B. OUTx upper limit: Lower limit of control output ~ 100%
C. OUTx lower limit: 0% ~ upper limit of control output
D. OUTx cycle time: Setting range: 1~600, units: 0.1 sec, default 50
